To all whom it may concern:

Be it known that I, JOHN B. CORNELL, of the city and county and State OfNew York, have invented a new and Improved Sash- VVeight; and I dohereby declare that the following is a full and exact descriptionthereof, reference being had tO the accompanying drawings, which form apart of this specification.

Figure l is a side view, and Fig. 2, a lon gitudinal section of saidsash-weight. i

In the hanging of window sashes within their frames, there hasheretofore been much dtliculty experienced in so perfectly balancing theopposite sides-Of the sashes that they would work freely and smoothly intheir frames.

' To obviate this difficulty is the Object of my present invention. y

The peculiarity of my improved metallic sash-weight, consists in itshaving a series of annular grooves b, b, formed therein, which commencenear to the lower extremity of the weight and thence extend u ward, atshort intervals from each other, or any desired distance, the saidgrooves being of suiicient depth to enable the lowest section,

or sections, to be knocked off, or Otherwise easily removed fromthesashlweight, when-i ever in the use of it it may be desirable to reduceitsfgravity.

The grooves b, b, in my improved sash weight, may be oftheformrepresented in" the drawings, or any other form that may bepreferred. My improved sash-weights I shall gener-` ally make ofcast-iron, but they may be manufactured of any other suitable metal or pmaterial.

What I claim as my invention and desire facture, is-

40 to secure by Letters Patent, as a new manu- My improved metallicsash-weighathe i peculiarity of which consists in its having a series Ofannular groovesformed at sultable distances from each other in the lowerportion of said'sash-Weight, for .the purpose i herein set forth.
